In 1756, one of the midshipmen on the Union was John Hunter, later to become an admiral and the second Governor of New South Wales.[2] On 1 August 1757 Arthur Phillip, who was to become the first Governor of New South Wales, joined the crew with the new commander.[3]

The results (published in 1796) of an experiment made at the desire of the Lords Commissioners of the Admiralty, on board the Union hospital ship, to determine the effect of the nitrous acid in destroying contagion, and the safety with which it may be employed were given in a letter addressed to the Right Hon. Earl Spencer, by James Carmichael Smyth, M. D. F.R.S., Fellow of the Royal College of Physicians, and Physician Extraordinary to His Majesty, published with the approbation of the lords commissioners of the Admiralty.[4]

In 1799, Union was converted to serve as a hospital ship.

In February 1802, she became a receiving ship and was renamed Sussex under Lieutenant John Rickman. In May 1807 Rickman was superseded by Lieutenant William Cockraft until she was paid off in Ordinary in March of 1816. In October of that year she was broken up at Chatham..[1]
